You need to put [ code] [/code ] tags around your examples so the formatting doesn't get lost.

I'd assume that the file contains just raw data and you want fixed width output. The printf command is probably what you want to use perhaps something like:

while read column
do
    printf "%-8s  "  "$column"
done < input.file
printf "\n"
3 
awk '$1=$1' infile
4 
$ ruby -ane 'puts $_.split.join(" ")' file
